Road Expert Panel


Our Road Expert Panel provides advice and support to our work as the Highways Monitor.

What’s the role and purpose of the panel?

The panel is advisory and will assist us by contributing expert insight on highways sector interests and issues. It should support us to deliver better outcomes for road users and wider stakeholders through our monitoring functions.

The panel will complement the existing expert panels within our organisation, such as the Consumer Expert Panel, and relationships with organisations such as Transport Focus.
